We are on a MISSION.

Welcome to real-time digital twin: an access-all-areas look at ours unconventional journey from crazy idea of using game engine to implementing within serious industry solutions over past six rollercoaster years. Digital twins are emerging as the best way for enterprises to compound value from digital transformation initiatives. For the industrial enterprise, digital twin use cases are primarily being adopted across engineering, operations, and service – driving significant business value and laying the groundwork for digital transformation across the enterprise. Learn how developing a digital twin strategy can help you harness the convergence of the digital and physical worlds.

Digital twin of construction sites.

To solve the problem of declining productivity within tunnel construction industry, full fledged digitisation with 3D geometry integrated with AI in underground geology prediction is required, which means either BIM at 4th level or real-time digital twins. Unlike BIM, digital twins provide near real-time update information, simultaneously as-built vs as-design information, geology 3D model of underground nearby to tunnel and can let collaborators to work on the model like Google document. 100% digital replica of construction site and equipments (TBM) connected with real-time sensors information and construction progress scanning with LiDAR can fix the problem of project scheduling, monitoring and future project planning which lets the productivity upscale.

Digital twin of smart cities.

Digital twins are considered to be a new starting point for today’s smart city construction. It is generally believed that the “Digital Twin” is a simulation process that makes full use of physical models, sensors, historical data of operation, etc. to integrate information of multi-discipline, multi-physical quantities, multi-scale, and multi-probability. It serves as a simulation process for physical products in virtual space. The essence of digital twins is a bi-directional mapping relationship that exists between physical space and virtual space. This bi-directional mapping is different from the unidirectional mapping, which only maps data from physical entities to digital objects.
